I had sliding doors like your design for my pots and pans cupboard...what a pain. Never enough room to get to what you need with only one side open at a time. I converted the doors last year to a
hinge opening, just like regular kitchen cabinets. works much better! Just make sure you use secure latches. I have a counter cover that goes over my Origo alcohol
stove; I like that it gives extra counter space when the
stove isn't in use. Mine drops back vertically into a slot at the back end of the counter so it's out of the way when the
stove is used. I like a lighter color counter top if the salon is small like my boat. Keeps it more open looking. You're on the right track though.
